Detailed Description

Add tips to your widgets

Gtk::Tooltip belongs to the new tooltips API that was introduced in GTK+ 2.12 and which deprecates the old Gtk::Tooltips API.

Basic tooltips can be realized simply by using set_tooltip_text() or set_tooltip_markup() without any explicit tooltip object.

When you need a tooltip with a little more fancy contents, like adding an image, or you want the tooltip to have different contents per Gtk::TreeView row or cell, you will have to do a little more work:

Call Gtk::Widget:set_has_tooltip(); this will make GTK+ monitor the widget for motion and related events which are needed to determine when and where to show a tooltip.
Connect to Gtk::Widget::signal_query_tooltip(). This signal will be emitted when a tooltip is supposed to be shown. One of the arguments passed to the signal handler is a Gtk::Tooltip object. This is the object that we are about to display as a tooltip, and can be manipulated in your callback using functions like Gtk::Tooltip::set_icon(). There are functions for setting the tooltip's markup, setting an image from a stock icon, or even putting in a custom widget.
Return true from your query-tooltip handler. This causes the tooltip to be show. If you return false, it will not be shown.

In the probably rare case where you want to have even more control over the tooltip that is about to be shown, you can set your own Window which will be used as tooltip window. This works as follows:

Do Gtk::Widget::set_has_tooltip() and connect to Gtk::Widget::signal_query_tooltip() as before.
Use Gtk::Widget::set_tooltip_window() to set a Gtk::Window created by you as tooltip window.
In the query-tooltip callback you can access your window using Gtk::Widget::get_tooltip_window() and manipulate it as you wish. The semantics of the return value are exactly as before, return true to show the window, false to not show it.

Member Function Documentation

◆ get_type()

static GType Gtk::Tooltip::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GtkTooltip* Gtk::Tooltip::gobj ( )

inline

Provides access to the underlying C GObject.

Definition at line 132 of file tooltip.h.

◆ gobj() [2/2]

const GtkTooltip* Gtk::Tooltip::gobj ( ) const

inline

Provides access to the underlying C GObject.

Definition at line 135 of file tooltip.h.

◆ gobj_copy()

GtkTooltip* Gtk::Tooltip::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ set_custom()

void Gtk::Tooltip::set_custom ( Widget & custom_widget )

Replaces the widget packed into the tooltip with custom_widget. custom_widget does not get destroyed when the tooltip goes away. By default a box with a Gtk::Image and Gtk::Label is embedded in the tooltip, which can be configured using set_markup() and set_icon().

Parameters

custom_widget A Gtk::Widget, or 0 to unset the old custom widget.

◆ set_icon() [1/2]

void Gtk::Tooltip::set_icon ( const Glib::RefPtr< Gdk::Pixbuf > & pixbuf )

Sets the icon of the tooltip (which is in front of the text) to be pixbuf. If pixbuf is 0, the image will be hidden.

Parameters

pixbuf A Gdk::Pixbuf, or 0.

◆ set_icon() [2/2]

void Gtk::Tooltip::set_icon	(	const Glib::RefPtr< Gio::Icon > &	icon,
		IconSize	size
	)

Sets the icon of the tooltip (which is in front of the text) to be the icon indicated by gicon with the size indicated by size. If gicon is 0, the image will be hidden.

Parameters

icon	A Icon representing the icon, or `0`.
size	A stock icon size.

◆ set_icon_from_icon_name()

void Gtk::Tooltip::set_icon_from_icon_name	(	const Glib::ustring &	icon_name,
		IconSize	size
	)

Sets the icon of the tooltip (which is in front of the text) to be the icon indicated by icon_name with the size indicated by size. If icon_name is 0, the image will be hidden.

Parameters

icon_name	An icon name, or `0`.
size	A stock icon size.

◆ set_icon_from_stock()

void Gtk::Tooltip::set_icon_from_stock	(	const StockID &	stock_id,
		IconSize	size
	)

Sets the icon of the tooltip (which is in front of the text) to be the stock item indicated by stock_id with the size indicated by size. If stock_id is 0, the image will be hidden.

Parameters

stock_id	A stock id, or `0`.
size	A stock icon size.

◆ set_markup()

void Gtk::Tooltip::set_markup ( const Glib::ustring & markup )

Sets the text of the tooltip to be markup, which is marked up with the Pango text markup language. If markup is 0, the label will be hidden.

Parameters

markup A markup string (see Pango markup format) or 0.

◆ set_text()

void Gtk::Tooltip::set_text ( const Glib::ustring & text )

Sets the text of the tooltip to be text. If text is 0, the label will be hidden. See also set_markup().

Parameters

text	A text string or `0`.

◆ set_tip_area()

void Gtk::Tooltip::set_tip_area ( const Gdk::Rectangle & rect )

Sets the area of the widget, where the contents of this tooltip apply, to be rect (in widget coordinates). This is especially useful for properly setting tooltips on Gtk::TreeView rows and cells, Gtk::IconViews, etc.

For setting tooltips on Gtk::TreeView, please refer to the convenience functions for this: Gtk::TreeView::set_tooltip_row() and Gtk::TreeView::set_tooltip_cell().

Parameters

rect	A Gdk::Rectangle.

◆ trigger_tooltip_query()

static void Gtk::Tooltip::trigger_tooltip_query ( const Glib::RefPtr< Gdk::Display > & display )

static

◆ wrap()

Glib::RefPtr< Gtk::Tooltip > wrap	(	GtkTooltip *	object,
		bool	take_copy = `false`
	)

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
